STACKER ATTAGIHVIENT.

Application filed October 30,1906. $erial No. 341,244.

Specification of Letters Patent.

Patented Aug. 13, 1907.

To all whom it may concern:

Be it known that I, WARREN A. Urnrorrr, a citizen of the United States, residing at Sandpoint, in the county of Kootenai, State of Idaho, have invented certain new and useful Improvements in Stacker Attachments; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to stackers and more particularly to the attachments therefor and has for its object to provide a retaining finger, a plurality of which may be attached to the teeth of the elevating sweep and which will be arranged to receive and hold hay deposited upon the sweep when the latter is in lowered position, but which will move into position to discharge the hay from the sweep when the latter is in raised position.

Another object is to provide an attachment which may be quickly and easily attached and removed.

Other objects and advantage will be apparent in the following description, and it will be understood that changes in the specific construction shown and described may be made within the scope of the claims,

without departing from the spirit of the invention.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views,

Figure l is a side elevation of a stacker with the elevating sweep in lowered position, the present invention being shown applied to the teeth ofthe sweep. Fig. 2 is an elevational view of one of the teeth with the attachment applied thereto. Fig. 3 is a top plan view. Fig. 4 is a longitudinal section of the tooth and its attachments, in the position which they occupy when the elevated sweep is raised, the finger being shown in side elevation. Fig. 5 is a transverse section in the plane of one of the yokes.

Referring now to the drawings, there is shown in Fig. 1a side elevation of a stacker including an upwardly movable elevating sweep including a plurality of parallel teeth 5. As will be readily understood, this elevating sweep lies in horizontal position when lowered, and in vertical position when raised, as is customary in apparatus of this sort. The present attachment includes a block 6 disposed upon a tooth of the sweep, each tooth 5 being provided with one of these blocks, and at its ends, the block is provided with transverse grooves 7 in its upper surface, which receive attaching yokes 8, the legs of the yokes extending downwardly at thesides of the block and tooth, and being connected at their lower ends by cross plates 9, through which the legs are engaged as shown, the legs having nuts (1 beneath these plates to prevent separation of the parts. -It will of course be understood that-the cross plates rest against the under surface of the tooth.

A longitudinally extending vertical slot 10 is formed in the block 6, the rearward end thereof being beveled upward and outwardly as shown at 1 1, and formed upon a block at opposite sides of the slot adjacent to the forward end thereof there are ears 12 which have engaged therein a transverse pin 13, a similar pin 14 being engaged in the block rearwardly of and below the pin 13 and extending across the slot. A finger 15 is pivoted upon the pin 14, for movement to lie at times in upwardly extending position against the pin 13 and at times to extend toward the fixed end of the tooth, resting against the beveled end of the slot. Thus, when the elevating sweep is in horizontal position to receive hay, the fingers extend upwardly and retain the hay upon the sweep until the latter has reached its vertical position, when the fingers will fall downwardly to allow discharge of the hay from the sweep.

It will readily be seen that the attachment may easily be placed in position and adjusted longitudinally of its tooth.

What is claimed is 1. The combination with a sweep tooth of a block so; cured thereupon and having a longitudinal slot therein, transverse pins engaged in the block and extending through the slot, one of said pins being located forwardly of and above the other, and a finger pivoted in the slot upon the rearward pin for movement to extend at times rear-wardly of the finger, and to lie at times against the forward pin.

2. An attachment for sweep teeth comprising a block having a longitudinal slot therein, transverse pins engaged in the block, one of said pins being located forwardly and above the other, and a finger pivoted upon the rearward pin within the slot for movement to lie at times against the forward pin and at times to extend rearwardly.

In testimony whereof, I afIix my signature, in presence of two witnesses.
